(Cl. 10S-225) 2 Claims.

The vpresent invention relates topump means or the like, particularlyfor pumping liquids, Vas `from wells, such as deep wells or the like.

Among the objects of the invention is to provide novel means for liftinga uid or liquidfrom a well, or the like, which is self-contained andprotected and which acts directly for best and most efcient results.

A further object of theinvention is to provide 4 novel means for sealingthe relatively ymoving parts of the pump whereby the greater the loadstress, the more efcient is the sealing means.

i Other objects, capabilities, advantages, features and the like arecomprehended by the invention as will later appear, and as areinherently possessed by theinvention.

Referring more in detail to the drawings, the embodiments selected toillustrate the invention are shown in association with a well cylinder lsurmounted by a cap 2 as at the top` of the ground 3, the cap 2 having adepending hub Il to which is fixed, as by screws 5 (see Fig. '7), theupper end of a pump delivery channel 5 connected at its lower end bysuitable coupling means or the like 'l to the upper end of a pump barrelor cylinder 8 extending down in the Well Cylinder I. At the lower end ofthe cylinder is any suitable strainer or the like 9, and in the lowerend of the cylinder B is a suitable inlet valve means I0 which may be ofthe check valve type, for effecting entry and iiow or lifting of liquidfrom the lower portion of the well cylinder I upwardly into the pumpcylinder 8.

Within the pump cylinder is vertically reciprocable a plunger pistonmeans Il, as shown in Fig. 8, or a plunger piston means I2, as shown inFigs. 1-5 of the drawings, which is suitably connected with the lowerend of a plunger rod I3 which extends and passes upwardly through thedevice as later more fully explained.

On the well cap 2 is a pump gearing housing I d (see particularly Figs.6 and 7) in which is rotatably mounted to rotate about a vertical axis aworm gear I5 as in a ball bearing means or the like I6, which gear isoperatively engaged with a driving worm I1 having a shaft I3 to theouter end of which is fixed a pulley or the like I9 over which runs adriving belt or the like 2d from a motor pulley or the like 2l xed to ashaft 22 of a motor 23 suitably supported on the ground 3 (see Fig. l)or a suitable base or floor 24 (see Figs. 8 and 9).

Upon the housing I ll is a pedestal member 25 having a base footing 26suitably set or lixed to the top part of the housing Irl, the membervZEhaving a suitable socket for a portion of the ball bearing means I6, andthe member 25 may be of any desired cross-sectional form, as square, or

round, or the like as desired. To the member 25 is xed, as by screws orthe like 2l, the lower end of an upwardly extending elongated channel orhousing 28 having at its upper end a head cap 29. See Figs. 8 andl'l inparticular.

The pedestal member 25 has a boring 3Q downwardly in which extends thelower end portion 3l of a double screw actuator member Si. extendingupwardly in the housing 28 and having a hub portion 33 at the upper endof the member 32 in the cap 29 (see Fig. 8). The lower portion 3| of themember 32 has a splined connection with a hub portion 35 of the gear I5,and the portion 3| has a downwardly extending sleeve 36 in the well cap2, for slidably guiding the plunger rod I3.

On the double threaded portion of the actuator 32 is operativelyassociated a cross-head 31 internally formed to f o eratively iit with'the double threaded part of the actuating member 32. To the endportions of the cross-head 31 are connected the lower ends of slide rods38 and 39, the upper ends ofwhich extend through and are slidablyreciprocable through and in the end portions of the cap 29 and at theupper and outer end portions of these rods 38 and 39 is xed a cross-head48. The upper end of the plunger rod I3 is fixed by suitable connectingmeans 4I to the central portion of the cross-head 40 so that thecross-head will reciprocate with the rods I3, 38 and 39. The upper endportion or hub 33 of the double screw actuator member 32 is rotatable inthe cap 29 and to the upper end part 42 (see Figs. 10 and 11) of thepart 33 is suitably secured a step or thrust bearing part 43 so that thedouble screw actuator may turn or rotate relative to the cap part 29,but the plunger rodY I3 only slides through the central bore 44. of theparts 32, 33 and 42.

The double screw actuator 32 has a set of races 45 of slow pitch (seeFigs. 10 and l1) so that as the cross-head 31 is raised thereby, as theactuator 32 rotates, it will move upwardly slowly as the plunger pistonmeans II or I2 raises the liquid; and has a set of races 46 of fastpitch so that as the cross-head 31 is caused to descend thereby as theactuator 32 rotates, it will move downwardly quickly and, hence, theplunger piston means l'I or I2V moves downwardly likewise quickly in theliquid in the pump cylinder 8.

The plunger piston means, as II or I2, may be of the particularconstruction shown in Figs. 12,

3, 4 and 5. Such means comprises a anged head 41 and a tubular body 48the upper end of which has` a Valve port 49 controlled by a valve 50. Onthe flanged part 41 is a cup-shaped sealing means I, the cylindricalwall of which sealingly and slidably contacts the inner wall of thepump-cylinder 8, and the upper. portion ofY the sealing means 5I has abevelled lip orV rim or the like 52 and cooperative withl the same is awedge ring 53 having atapered surface or face 54 cooperative with thebevelled surface 52' to force and maintain the cylindrical. wall of themember 5I in sealing contact with the. inner Wall of the pump cylinder8.

Within the ring 53 and between it and the tubular body part 48 is akeeper ring 55 which also has a bevelled or wedge part 56 acting againsta ring 53v to maintain the latter stressed against the tapered or wedgepart 52 of a' sealing cup 5 I.v

The wider part' of theV ring 53 has a depression or depressions 53a,53h, or grooves or the like, for aiding the sealing effect of said ring53, on cup 5I. The keeper ring 55 is forced down or stressed by a secondcup shaped' sealing means 51 which is pressed down by the base orskirted portion58' of a valve case or cage 59. threaded' to the threaded portion 6U of the tubular body part 48. The. upper rim portion of thesealing cup 51 has a tapered part or wedge part EI against which isstressed the lower tapered or wedge rim portion 82 of a follower orkeeper 63 having a top part 64 against which is stressed a coil spring55 compressed under a cross pin or the like 66 in the plunger rod I3.The wedge parts 6I and 62 act to maintain the wall of the cup 51 insealing contact with the wall of the pump cylinder 8. The top part 54has a bore or throat 61 for upward passage of liquidwhen the plungerpiston means is forced down in the liquid column in the pump cylinder 8.

'I'he valve cage 59 has4suita'ble side openingsl 58 also for passage ofthe liquid from the valve port 49 to and through the bore or throat 61,and also has a top 69 to which the lower end of the plunger rod I3 issuitably fixed. When the rod I3 is reciprocated on a down stroke, liquidis forced upwardly by way of the tubular member 48, valve port 49,openings 88, and bore 61 thence into the cylinder 8, and on theup-stroke the valve 5I) closes and the liquid above it is moved upwardlyin the cylinder 8 tov and through a piston type' of; wall 13 providedyin the upper part of the cylinder 8, and thence by way of the pipe 10(-see Fig. 7) connected at its lower end to the wall 'I3 and incommunication with the chamber of cylinder 8, the pipe 10 extending upthrough the chamber. 6 and in communication with duct 1I provided in thehub 4, and thence by way of a delivery pipe 12.

Inoperation the motor 23 operates through the belt to the worm I1 andthe gear I5 to rotate the actuator 32. The latter causes areciprocati'on of' the cross-head 31" and hence the rods 38 and 394 andthe cross-head 40. The'lat-ter causesa reciprocation of the plunger rodI3 and hence the plunger piston II or I2" and hence thev liquid in thewell IA is lifted and forced out by way of the delivery or dischargeduct 12. Onthe upstroke ofv the plunger piston means I2, the force orweight of the liquid forces the wedgey parts 52 and 53, as also thewedge parts 6I and 62, to maintain a liquid-tight seal of the cupmembers 5I and 51 with the wall of the pump cylinder 8. If these wedgeparts wear, thereis an automaticv take up in compensation of any suchWear So that the complete' and efficient sealing effect willI bemaintained.

While I have herein' described and upon the` drawings shown an'illustrative embodiment or embodiments ofthe invention, it is to beunderstood that the invention is not limited thereto but comprehendsother constructions, details, arrangements of parts, features, andthelike with-V v out departing from thespirit' of the invention.
